- norE-rnAsiNe MECHANISM.

To aZZ whom it may concern:

Be it known that we, JOHN WILLIAM Bonn and HENRY ARTHUR Bonn, subjects ofthe King of Great Britain, both residingfat the type wherein the rope is passed in the direction of the axis of rotation through a right angled nozzle rotating at considerable speed so as to cause the end to rapidly whirl around in a plane at right angles to the axis of rotation and cause such end to be brought against a teasing device locatedv in the path of the rope paid out fromthe said nozzle.

The present invention has for its object certain improvements in machines of this kind, these improvements being characterized in that stationary teasing spikes-are fixed in the plane of rotation of the rope end so as to project from'theinside of the casing within which the nozzle rotates and in that the said casing is so shaped as to form a guide for the end of the rope whirled around by the said nozzle so'asto direct it against the spikes, whereby the breaking up and teasing operation is accomplished in a more efficient and expeditious manner than hitherto. These and other improvements will be understood from the followingde scription reference being had to the accom panying drawings in which Figure l is a side elevation of one spindle machine having a part of the casing removed for the purpose of better illustration,

Fig. 2 is a front elevation,

Fig.3 is a plan view, and

Fig. 4 is an enlarged detail view of the nozzle.

In these figures, 1 are the side frames of the machine, 2 is the driving shaft journaled in bearings in the said side frames and provided with fast and loose pulleys 4, 5 driven from a line of shafting, 6 is a two speed pulley on the end of the shaft'2 for imparting motion by means of belting to a two speed pulley 7 keyed on a countershaft 8. Journaled in bearings on the side frames is a shaft 9 having a pulley 10 or 1O driven Specification of Letters Patent.

Application filed July 7, 1919. Serial No. 308,959.

from a pulley 11 or 11" on the driving shaft '2, and attached to one end of theshaft 9 is a nozzle 12 turned'at right angles at 13 and having a counterweight 14. The inlet 15 of this nozzle is in close proximity to the bracket 16 which is supported on the frame 1, this bracket being made in two halves between which are mounted top and bottom corrugated or spiked feed rolls 1?, 18 secured on shafts 19, 20, motion being im parted to the shaft 19 by the worm wheel 21 gearing with the worm 22 on the shaft 8. The shaft 20 is driven by gear wheels 23, 24 from the shaft 19. The shaft 20 is mounted in hearings in the bracket 16 and has a free vertical movement so that the feed rollers 1'7, 18 may adapt themselves to the varying diameters of ropes to be fed to the machine,

the teeth of the wheels 23, 24 being of suificient length to remain in gear notwithstanding any variation in the distance between the shafts 19, 20 due'to the varying diameter of rope fed to the machine. The shaft 20 is pressed downward by weights 25 at the upper ends of rods 26 which are mounted in guides the lowerends of these rods having foot pieces 27 resting on the shaft 20. Thus while the roll 18 can readily accommodate itself to the size of the'rope entering between the rolls, such weights will tend to keep the roll 18 pressed downward toward the roll 17. The revolving nozzle 12 is inclosed by a hood or casing 28 so shaped and of such width as to confine and form a guide for the end of the. rope whirled around by the end of the nozzle 12. Secured to this hood 28' on the inside and in proximity to the nozzle are a plurality of teasing spikes or teeth 29 to pull apart or tease the rope. These spikes are driven or screwed through perforations in the hood so as to project on the inside thereof. 'This teasing device 29 is stationary and has no moving parts, and

avoids the necessity of using a rotary teasing cylinder separate from the hood and the guiding of the rope onto these teasing spikes 29 by the hood 28 performs the teasing operation very effectively and in many cases in a superior manner to a revolving teaser. The hood 28 has flanges 3O projecting from it which are respectively bolted at 31 to an arm 32 projecting from the two part bracket 16 and to the bracket 33 secured to the frame 1, these flanges 30 being slotted at 34 for the bolts 31 to pass through, so that by loosening the nuts on the bolts the hood can be adjusted to move the teasing spikes away from or nearer to the revolving nozzle 12 as may be required according to the quality of rope that is being broken up. The -hood 28 is open at the end 36 to permitof the discharge of the material and for. part of its -lengt-h at the sides as shown at 35 t'o permit of being placed in the nozzle 12. V V The mode of action is as fOllOWSZ-'Tl16 position and moved over machine having been set in motion, the end of a rope to be teased is started between the commodates itself to the size of the rope i entering between the rolls,- and the rope is drawn in between the rolls by the .corruga .tions or spikes carried by the latter.- After passing between the rolls, the rope passes into the axial inlet 15 of, the angular nozzle This nozzle rotates at high speed with the shaft9, and its. passage being bent at right angles at 18, the rope passes out of the nozzle in a direction radial to the axis offrotati'on of the nozzle, and is whirled around in a plane approximatelynormal to c the axis of rotation of the nozzle, centrifugal force tending to hold the end of the rope out radially and to draw an increasing length of rope from thenozz'le. The nozzle pas= sage may be roughened at 13 and this causes suff cientfrictional engagement between the nozzle and the rope to produce an HntWlStf ing of the rope between. the feed rolls and the portion 13 of the nozzle, the direction of rotation-of thenozzle being opposite to the I direction of twist of the rope.

The rope being thus untwisted and loosened, the shorter fibers fly'off by centrifugal forecouleaving the nozzle, but the main'portion of the rope .end whirls around and being guided by the-"hood is repeatedly struck upon theteasi-ng spikes 29 sothat the ropeend is disintegrated as fast as fed forward. In this separated or divided state it is discharged from the open end 36 of the hood 28.; The process of teasing the rope is thus a continuous one and includes four elements,- first the untwisting,- second a centrifugal disintegration, third disintegration by inn pact upon the teasing spikes and fourth a I combing action as the end of the rope is drawn across the teasing spikes. Itha-s been found desirable to have considerable range of adjustment of the distance between the rotary nozzle and the teasing spikes to teasing machine, the combination with a rotary right angled nozzle having guide passage adapted to receive a rope through its axial arm and discharge it through the radial one, of stationary teasing spikes fixed i in the plane ofrotation of the rope end, and

a hoodor casing so shaped as to form a a guide for the end.- of the rope whirled around by the said radial arm so as to. direct it against the spikes.--
